Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vertical height sensors are used in user equipment, then location detection capability is provided, but measurement precision deteriorates due to sensor limitations in tall buildings
Solution Approach 1:
The patent combines vertical height measurements from multiple user equipment devices within the same building. By merging data from multiple sensors across different devices, the system overcomes the limitations of individual sensors and achieves more precise floor level determination through collective measurement and cross-validation.
Solution Approach 2:
The patent introduces a server as an intermediary that receives vertical height data from multiple user equipment devices, processes this information, and determines the accurate floor level. The server acts as a mediator that coordinates measurements from multiple sources and provides corrected location information to emergency services.
2Measurement precision
If single sensor data is used for vertical height detection, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent merges vertical height measurements from multiple user equipment devices to achieve higher precision. While this increases system complexity, the distributed nature of the solution allows each individual device to remain relatively simple while the collective system achieves accurate floor level detection through data aggregation and processing.
3Measurement precision
If multiple user equipment are used for location detection, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary that manages the complexity of coordinating multiple user equipment devices. The server handles data aggregation, cross-validation, and floor level determination, allowing the individual devices to focus on simple sensor measurements while the centralized system manages the overall complexity and provides accurate location information.
